!
The pollen filter is located in front of the blower unit behind the glove box. It operates to decrease pollutants en- tering the car and to filter the air.To replace the pollen filter, refer to page 6-26. CAUTION:
o Replace the filter every 10,000 miles or once a year. If the car is being driven in severe conditionssuch as dusty, rough roads, more frequent air filter inspections and changes are required.
o When the air flow rate is suddenly decreased, it must be checked atan Hyundai authorised repairer.

B750A02A-AAT How Car Audio Works AM and FM radio signals are broadcast from transmitter towers located around your city. They are intercepted by theradio antenna on your car. This signal is then received by the radio and sent to your car speakers.When a strong radio signal has reached your vehicle, the precise engineering of your audio system ensures high qualityreproduction. However, in some cases the signal coming to your vehicle is not strong and clear. This can be dueto factors such as the distance from the radio station, closeness of other strong radio stations or the presence of build-ings, bridges and other large obstruc- tions in the area.STEREO SOUND SYSTEM

o Fading - As your car moves away from the radio station, the signal will weaken and sound will begin to fade. When this occurs, we suggest that you select another stronger station.
o Flutter/Static - Weak FM signals or large obstructions between the trans-mitter and your radio can disturb thesignal causing static or fluttering noises to occur. Reducing the treble level may lessen this effect until thedisturbance clears.
AM broadcasts can be received atgreater distances than FM broadcasts. This is because AM radio waves are transmitted at low frequency. Theselong, low frequency radio waves can follow the curvature of the earth rather than travelling straight out into the at-mosphere. In addition, they curve around obstructions so that they can provide better signal coverage.
FM broadcasts are transmitted at highfrequency and do not bend to follow the earth's surface. Because of this, FM broadcasts generally begin to fade at short distances from the station. Also, FM signals are easily affected by build-ings, mountains, or other obstructions. These can result in certain listening conditions which might lead you tobelieve a problem exists with your ra- dio. The following conditions are normal and do not indicate radio trouble:

o Station Swapping - As a FM signalweakens, another more powerful sig- nal near the same frequency may begin to play. This is because your radio is designed to lock onto the clearest signal. If this occurs, selectanother station with a stronger sig- nal.
o Multi-Path Cancellation - Radio sig- nals being received from several di-rections can cause distortion or flut- tering. This can be caused by adirect and a reflected signal from the same station, or by signals from two stations with close frequencies. Ifthis occurs, select another station until the condition has passed. B750B02Y-AAT Using a cellular phone or a two- way radio When a cellular phone is used inside the vehicle, noise may be produced from the audio equipment. This doesnot mean that something is wrong with the audio equipment. In such a case, use the cellular phone at a place as faras possible from the audio equipment.
!
CAUTION:
When using a communication sys- tem such as a mobile phone or aradio inside the vehicle, a separate external antenna must be fitted. When a mobile phone or a radio set isused with an internal antenna alone, it may interfere with the vehicle's electrical system and adversely affectsafe operation of the vehicle.
!WARNING:
Don't use a mobile phone when you are driving, you must stop at a safe place to use a mobile phone.
